π-Extended TTF: a versatile molecule for organic electronics

Electroactive carbon nanoforms: a comparative study via sequential arylation and click chemistry reactions

“…In addition to the absorption assays, we subjected pristine 10 SWCNTs, SWCNT-1 and SWCNT-2 to fluorescence measurements in DMF. Accordingly, measurements performed with pristine SWCNTs reveal maxima at 1057, 1128, 1211, 1305, and 1419 nm, which correspond to (10,2), (7,6), (11,3), (13,2), and (9,8) SWCNT, respectively (Figure 8). 31 It is important to 15 note that the fluorescence features mirror image those seen in the absorption measurements.…”

New Iridium Complex Coordinated with Tetrathiafulvalene Substituted Triazole-pyridine Ligand: Synthesis, Photophysical and Electrochemical properties

“…The photophysical and electrochemical properties have been measured and analyzed. The luminescent spectra show that the emissive state originates from mixed intraligand and metal-to-ligand charge transfer 3 (π→π * + MLCT) transitions. The electrochemical studies reveal that 1 undergo reversible TTF/TTF +· /TTF 2+ redox processes and one irreversible Ir 3+ →Ir 4+ oxidation process.…”

“…For several decades, tetrathiafulvalene (TTF) and its derivatives were extensively developed by scientists in photofunctional materials [1][2][3][4][5][6][7][8] because of their strongly electron-donating and attractive reversible redox properties. As a consequence, a large synthetic effort has also been devoted to the preparation of materials that exhibit synergy or coexistence between conductivity and luminescence.…”

The Revival of Fullerenes?

“…11 In contrast, while the supramolecular chemistry of TTF is nowadays a well-trodden path, that of its π-extended analogues has remained virtually unexplored.…”
